    摘要： A method is provided including generating touch coordinate information corresponding to touch interactions with a touchscreen display of an electronic device and updating information rendered on the touchscreen display in response to determining that the touch coordinate information matches a tool shaft movement gesture corresponding to movement of a touch tool shaft over an area of the touchscreen display. A device is provided, including a touchscreen display comprising a display and a touch sensing system configured to generate signals corresponding to screen touches of the display, a processing device operatively coupled to the touchscreen display, and a non-transitory memory coupled to the processing device and storing software instructions that when executed by the processing device configure the processing device to carry out the provided method. The ability to process tool shaft gestures may improve one or both of the operation of the device and the user experience with the device.

    摘要： Methods of detection of swipe gestures and filtering and locating desired information in a multi-attributed search space in response to detection of swipe gestures and devices for performing the same are provided. The method includes activating an attribute associated with at least one element of a list of elements having a visible list portion rendered on the viewing area, in response to receiving an activation input for the attribute and displaying a plurality of attribute field controls associated with the attribute, in response to its activation. The method further includes receiving a manipulation action of at least one attribute field control, updating an attribute value in response to the manipulation action, and updating the visible list portion based on the attribute value. The method may be used with touchscreen displays, and with virtual or augmented reality displays.

    摘要： A gesture-controlled device and a method thereon are provided. The method includes capturing a plurality of video frames of a user's body and processing the plurality of video frames to allow detecting a portion of the user's body and to allow recognizing hand gestures. In response to detecting the portion of the user's body, the method includes generating at least one widget interaction region corresponding to the portion of the user's body. The method further includes recognizing, a mid-air hand gesture in the at least one widget interaction region, mapping the mid-air hand gesture to at least one virtual widget on the gesture-controlled device, and manipulating the at least one virtual widget based on the mid-air hand gesture. The method and device allow manipulation of virtual widgets using mid-air gestures on a gesture-controlled device.
